Application filed May 13,1907. Serial No. 373,272.

nozzles useful in connection with vessels of various kinds, butespecially applicable to ink-bottles in order to provide for fillingfountain pens direct from the same.

Figure 1 of the drawings represents a vertical transverse section viewof a vent-nozzle in accordance with my invention applied to a bottle, afragment of which bottle is shown partly in section, and Fig. 2, a planview of the nozzle.

Referring by letter to the drawings, A indicates a sheet-metal screw-caphaving a central top slot be tween struck-up ears b and soldered to thecap-top and its ears is a preferably tapered and horizontally disposedspout B provided with a longitudinal slot in register with the oneaforesaid, the length and arrangement of the spout being such that itsends project beyond said cap. A compression gasket C is arranged in thecap-portion of the nozzle so that the same may have air-tight union withthe mouth of the vessel to which it is applied, and one end of the spoutis provided with a cover D in screw-thread connection there with. Byadjustment of the cover D, the spout may be vented to regulate flow offluid contents of the vessel through the opposite end of said spout,this fiow being in drops or a fine stream as may be most desirable, and

it follows that if the nozzle be employed in connection with anink-bottle, it is practical to fill fountain-pens with ink direct fromsaid bottle.

A nozzle-spout having a bore of varying diameter and provided with ascrew-cover for that end of the bore having the greatest diameter ispreferred, as on removal of said cover, the fluid-contents of the vesselto which the nozzle is attached may be poured rapidly through thecover-end of said spout, vent being had through the opposite end Wherethe bore is of least diameter. As a matter of economy the spout having abore of varying diameter is preferably a tapered tube of sheet-metalprovided at its largest end with a screwthreaded cylindrical fitting r:of the same material for the engagement of the correspondinglyscrew-threaded cover D that is also preferably of sheet-metal.

I claim:

1. A vent-nozzle comprising a cap having a slotted top, a spouthorizontally disposed on the cap-top in communication with the slot ofsame, and a cover having screwthreaded engagement with one end of thespout.

2. A vent-nozzle comprising a cap having a slotted top, a spout ofvarying diameter bore horizontally disposed on the captop incommunication with the slot of same. and a cover having screw-threadengagement with that end of the spout having the greatest bore.

2;. A vent-nozzle comprising a cap having a slotted top. a taperedsheet-metal tube horizontally disposed on the cap top in communicationwith the slot of same to constitute a spout, and a screw-cover on thelargest end of the spout.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee in the county of Milwaukee and State of Wisconsin in thepresence of two witnesses.
